Down to the wire for silicon: Researchers create a wire four atoms wide, one atom tall

Down to the wire for silicon: Researchers create a wire four atoms wide, one atom tall | anti dogmanti | Scoop.it
The smallest wires ever developed in silicon -- just one atom tall and four atoms wide -- have been shown by a team of researchers to have the same current-carrying capability as copper wires.

 

Wires just one atom tall have been created by inserting a string of phosphorus atoms in a silicon crystal by a team of researchers from the Univeristy of New South Wales, Melbourne Univeristy and Purdue University. This image from a computational simulation run of the wires shows electron density as electrons flow from left to right. The wires are 20 times smaller than the smallest wires now available and measure just four atoms wide by one phosphorus atom tall.

 

Bent Weber, the paper's lead author and a graduate student in the Centre of Excellence for Quantum Computation and Communication Technology at the University of New South Wales, was thrilled with the finding.
"It's extraordinary to show that Ohm's Law, such a basic law, still holds even when constructing a wire from the fundamental building blocks of nature -- atoms," he says.

Over 65 million years North American mammal evolution has tracked with climate change

Over 65 million years North American mammal evolution has tracked with climate change | anti dogmanti | Scoop.it
Climate changes profoundly influenced the rise and fall of six distinct, successive waves of mammal species diversity in North America over the last 65 million years, shows a novel statistical analysis led by Brown University evolutionary biologists.

 

"Such perturbations, related to anthropogenic climatic change, are currently challenging the fauna of the world today, emphasizing the importance of the fossil record for our understanding of how past events affected the history of faunal diversification and extinction, and hence how future climactic changes may continue to influence life on earth," the authors wrote in the paper.

Announcing the 2012 TED Prize Winner – The City 2.0 | anti dogmanti | Scoop.it
TED Prize Winner Updates and Input...

For the first time in the history of the prize, it is being awarded not to an individual, but to an idea. It is an idea upon which our planet’s future depends.

The TED Prize grants its winner $100,000 and “one wish to change the world.” How will this prize be accepted on behalf of the City 2.0? Through visionary individuals around the world who are advocating on its behalf.

We are listening to them and giving them the opportunity to collectively craft a wish. A wish capable of igniting a massive collaborative project among the members of the global TED community, and indeed all who care about our planet’s future. (Individuals or organizations who wish to contribute their ideas to a TED Prize wish on behalf of The City 2.0 should write to tedprize@ted.com)

Higgs boson 'to be found' at Cern

Higgs boson 'to be found' at Cern | anti dogmanti | Scoop.it
A respected scientist from the Cern particle physics laboratory says he expects to see "the first glimpse" of the Higgs boson next week. Professor Ellis, who is now a guest professor at Cern, and was recently made James Clerk Maxwell professor at King's College, London, told Newsnight that finding the Higgs matters hugely to modern physics.

"What we have at the moment is something we call the Standard Model, that describes all fundamental particle physics. You can think of it as being an enormous giant Jigsaw puzzle, but there's a piece missing right in the middle there. We have been looking for this for 30 years now, and finally, maybe, hidden under the back of the LHC sofa…we are finally finding it".

Sam Harris interviews Lawrence M Krauss, a renowned cosmologist, popularizer of science, and director of the Origins Project at Arizona State University. He is the author of more than 300 scientific publications and 8 books, including the bestselling The Physics of Star Trek. His interests include the early universe, the nature of dark matter, general relativity and neutrino astrophysics. He is also a friend and an advisor to my nonprofit foundation, Project Reason. Lawrence generously took time to answer a few questions about his new book, A Universe from Nothing.

Couple finds evidence indicating earliest humans lived by rivers and streams

Couple finds evidence indicating earliest humans lived by rivers and streams | anti dogmanti | Scoop.it

When many people think of our earliest human ancestors, they think of the hot dried out dusty environments in Africa in which many of their remains were found.

 

Unfortunately, such images don’t take into account the changes in environment that have occurred since those times when early peoples walked the Earth. Archeologists of course have thought of such things and for many years have tossed ideas back and forth debating whether such people lived by rivers and streams, as did those that came later and built civilization along such places as the Nile or whether they lived in woodlands.

Astronomers confirm 'Earth twin' | anti dogmanti | Scoop.it

Astronomers confirm the existence of an Earth-like world orbiting a star like our Sun in its "habitable zone" - at a balmy 22C. The Kepler space telescope was designed to look at a fixed swathe of the night sky, staring intently at about 150,000 stars. The telescope is sensitive enough to see when a planet passes in front of its host star, dimming the star's light by a minuscule amount.
